Data Services Products: SWS-DB the Géosciences Montpellier SplitLab Shear-Wave Splitting Database

Summary

Description

IRIS, in collaboration with the Géosciences Montpellier, France, has created the SplitLab Shear-Wave Splitting Database (SWS-DB-SplitLab) as a mirror of the Géosciences Montpellier's SplitLab Shear-wave splitting database. Even though this mirror database is updated with the most recent copy of the Géosciences Montpellier's database on a daily basis, users may still notice the following differences between the data downloaded from here and those available from the Géosciences Montpellier.

  • records with incomplete or missing station information (code, latitude or longitude) are omitted
  • a zero value is assigned to dt for all records with null phi
  • phi values range between 0° and 360°

Access to the SplitLab SWS-DB at IRIS is available via SPUD where user can easily search the SWS-DB data using the geographic areas, the station code or via SPUD's customized interactive Google Maps.

Credits

  • The Shear-Wave Splitting database was created and is maintained by the SplitLab group at Géosciences Montpellier. The database is kept updated by the ongoing efforts of Guilhem Barruol, lab Géosciences Réunion, Université de la Réunion, Institut de Physique du Globe de Paris, CNRS, contact:guilhem.barruol@univ-reunion.fr.

  • The initial compilation of published shear wave splitting values was generated by Derek Schutt at the University of Oregon in the late 1990s and was maintained by him at Carnegie’s Department of Terrestrial Magnetism.
  • From 2001 to 2006, the list was maintained updated at Arizona State University by Matt Fouch.
  • In March 2012, in collaboration with the Géosciences Montpellier, IRIS DMC started mirroring the Shear-wave Splitting Database.
